Abstract
In this paper the design of a high directivity antenna at terahertz regime for using in imaging applications and a chiral metamaterial cover, which enhances the radiation pattern of the antenna, are presented. The structure of the antenna is based on a linear array of planar patches fed by a distribution of slots working in W-band and it presents low cost and easy manufacture. On the other hand, the chiral metamaterial cover is constituted by two layers of mutually twisted planar metal rosettes in parallel planes suitable to operate in W-band. In order to compare the features of both designs, without and with the cover, numerical results of the radiation pattern of both structures are compared.
